Concrete Material Values

[soccer8888]

I'm doing an analysis using a concrete pedestal holding a device that has a number of loads and moments acting upon it.


When specifying the materials for the concrete, I added the density, Poisson's ratio, Youngs Modulus and CTE that was found for common concrete. After the analysis ran,the results showed little stress but relatively high deflection from the device 'sinking' into the concrete. Displacement was up to .2 of an inch. Can anyone give me insight into a)how to better model the material, or b)another way to simulate the effect of concrete? I don't want to just fix the pedestal either.

Check your units of the model with respect to the young modulus. You should be using units of IPS not the default ProE.

Yeah, I had checked that and everything is correct. I'll double-check it just to make sure, but are there any other possibilities?

Edit the material properties of the concrete from Pro/mechanica and make sure the Young modulous is magnitude is the correct one.

Does anyone have the/an actual value for that. Its correct from what I have, but maybe I'm just using the wrong Youngs Modulus.

 

[Luis Aguirre]

Could you tell me what the magnitude and units of your young modulus as appears on your model?

The value I am using is 3605 ksi

 

[zachary_popov]

might be the correct value for your case should be 3605E+03 ksi (3605E+06psi).
